CORD SETS AND CONNECTOR PLUGS

120 VOLTS DUPLEX RECEPTACLE

Use only high quality, well-insulated, extension cords

with the 120-volt =duplex" type electrical receptacles

(Fig. 1). All cord sets used should be rated 125 volts at

15 a-c amps or greater for most electrical devices.

Keep extension cords as short as possible, preferably

less than 15 feet long to prevent voltage drop and wires

from overheating.

GROUNDING THE GENERATOR

The National Electrical Code requires that the frame and

external electrically conductive parts of this generator be

properly connected to an approved earth ground. Local

electrical codes may also require proper grounding of the

unit. For that purpose, a GROUNDING WING NUT is

provided on the base of the cradle (Fig. 3). Generally,

connecting a No. 12 AWG (American Wire Gauge)

stranded copper wire to the grounding lug and to an earth-

driven copper or brass grounding rod (electrode) provides

adequate protection against electrical shock. Be sure to

keep ground wire attached when you connect electrode.

However, local codes mayvary widely. Consult with a local

electrician for grounding requirements inyourarea. Proper

grounding of generator will help prevent electrical shock in

the event of a ground fault condition in the generator or in

connected electrical devices. Proper grounding also helps

dissipate static electricity, which often builds up in un-

grounded devices.

the yellow Oil Fill Caps (Fig. 4) and add engine oil until

level is at point of overflowing. Check engine oil level

before startingeach time thereafter. Ifoillevel is below

point of overflowing, fill to proper level. The recom-

mended oils include (during summer months) SAE 30

oil. SAE 10W-30 is an acceptable substitute. During

winter months use SAE 5W-20 or 5W-30. DO NOT

USE 10W-40. Crankcase oil capacity is about 620ml

or 21 fluid ounces.

• When engine starts, open choke gradually.

CONNECTING ELECTRICAL LOADS

Letengine stabilize and warm up for about five minutes

after starting.

Plug in and turn on the desired 120 or 240 volts, single

phase, 60 Hertz, a-c electrical loads.

DO NOT connect 240 volts to 120 volts duplex recep-

tacles.

DO NOT connect 3-phase loads to panel receptacles.

DO NOT connect any 50 Hz loads to the generator.

Add up the rated watts of all lights,tool, appliance and

motor loads you are powering at one time. This total

shouldNOT be greater than (a) generator"_rated watt-

age capacity or (b) circuit breaker rating of the recep-

tacle supplying the power.

STOPPING THE ENGINE

• Disconnect all electrical loads and let engine run at

no-load for about five minutes to stablize intemal tem-

peratures of engine and generator.

• Turn off the engine by moving the Run/Stop switch to

STOP position.

OPERATION

LOW OIL PRESSURE SHUTDOWN SYSTEM

The engine isequipped with a low oil pressure sensor that

shuts down the engine automatically when the oilpressure

drops below 6 psi. If the engine shuts down by itself and

the fuel tank has enough gasoline, check engine oil level.

INITIAL STARTUP

A delay built in the shutdown system allows oilpressure to

buildduringstarting. The delay allows the engine to runfor

about 10 seconds before sensing oil pressure.

SENSING LOW PRESSURE

If the system senses low oilpressure during operation, the

engine shuts down. As the system shuts down, the low oil

light comes ON. However, once the engine has stopped

rotating, this lightwill go OFF.

RESTARTING

Ifyou try to restart the engine within 5 seconds after it shuts

down, the engine may NOT start. The system needs 5 to

10 seconds to reset.

If you do restart the engine after such a shutdown and

have not corrected the low oil pressure, the engine

runs for about 10 seconds as described above and then

stops.

DON'T OVERLOAD THE GENERATOR

Overloading a generator in excess of its rated wattage

capacity can result in damage to generator and to con-

nected electrical devices. Observe the following, to prevent

overloading the unit:

• Add up the total wattage of all electrical devices to be

connected at one time. This total should NOT be

greater than the generator's wattage capacity.

• The rated wattage of lights can be taken from light

bulbs. The rated wattage of tools, appliances and

motors can usually be found on a data plate or decal

affixed to the device.

• If the appliance, tool or motor does not give wattage,

mulitply 120 volts times ampere rating to determine

watts (volts x amps = watts).

• Some electric motors, such as inductiontypes, require

about two-and-a-half times more watts of power for

startingthan for running. This surge of power lasts for

onlya few seconds when starting such motors. Be sure

you allow for this high starting wattage when selecting

electrical devices to connect to your generator. First

figure the watts needed to start largest motor. Add to

that figure runningwatts of all other connected loads.

• The GUIDE below is provided to assist you in deter-

mining how many items your generator can operate at

one time.

SERVICE AND ADJUSTMENTS

ENGINE SPEED

CAUTION: ENGINE SPEED WAS PROPERLY AD-

JUSTED AT THE FACTORY AND SHOULD RE-

QUIRE NO ADDITIONAL ADJUSTMENT. DO NOT

_k ATTEMPT TO CHANGE ENGINE SPEED. IF YOU

BEUEVE THE ENGINE IS RUNNING TOO FAST OR

TOO SLOW, TAKE YOUR GENERATOR TO

AUTHORIZED SERVICE CENTER FOR REPAIR

AND ADJUSTMENT. CHANGING ENGINE GOV-

ERNED SPEED WILL VOID ENGINE WARRANTY.

Your generator runs at a constant speed. This constant

operaUng speed is maintained by a mechanical, flyweight

type, fixed speed governor. DO NOT try to adjust the

governed speed setting for the following reasons:

• High engine speeds are dangerous and increase the

riskof personal injuryor damage to equipment.

• Low engine speeds impose a heavy loadon the engine

when sufficient engine power isnot available and may

shorten engine life.

• The generator will supply correct rated AC frequency

and voltage onlyat the proper speed. Some connected

electrical devices could be damaged by incorrect fre-

quency and/or voltage.

ADJUSTING THE CARBURETOR

The carburetor of your generator is preset at the factory.

DO NOT TAMPER WITH THE CARBURETOR, as this will

void the emission control system warranty. If your gener-

ator is used at altitudes above 5,000 feet, you should

consult with an authorizes Sears Service Facility regarding

high altitude jetting changes.

ADJUSTING VALVE CLEARANCE

After the first 50 hours of operation, you should adjust the

valve clearance in the engine.

When adjusting valve clearance, the engine should be at

room temperature and the piston should be at Top Dead

Center (TDC) of its compression stroke (both valves

closed). Correct clearance is 0.05-0.1mm. Adjust valve

clearance as follows:

• Loosen the rocker arm jam nut. Use an allen wrench

to tum the pivot ball stud while checking clearance

between the rockerarm and thevalve stem with a feeler

gauge (Fig. 121.

• When valve clearance is correct, hold pivot ball stud

with allen wrench and tighten rocker arm iam nut with

a crows foot. Tighten the jam nut to65-85 mch-pounds

torque. After tightening the jam nut, recheck valve

clearance to make sure itdid not change (Fig. 13).
